What this song renders
Yoshinaka’s death at Awazu in February 1184 ended the Kiso branch of the Minamoto as a political force. He was thirty years old. His army had been one of the two principal Minamoto commands; with him gone, his cousin Yoritomo had no rival within the family. The Genpei War would continue for another year, ending at Dan-no-ura in 1185, but the internal Minamoto question was settled at Awazu.
The Heike Monogatari’s last note on Tomoe is that she rode east. After this the chronicle does not return to her. What happened to her in the years following is the subject of a number of later traditions, none of them confirmed. The most-repeated has her becoming a Buddhist nun and praying for Yoshinaka’s soul; another has her taken or married by the warrior Wada Yoshimori, with whom she is said to have had a son. Both stories postdate the events by centuries and conflict with each other.
The album does not pick between the post-Heike traditions. It renders only the morning after — the documented departure, the silence the chronicles preserved by accident, the fact that whatever happened next, it happened to a survivor of Awazu. The dynasty falls. The rider does not.
Yoshinaka’s death and the political end of the Kiso line are well-documented. Tomoe’s departure east is in the Heike. Anything beyond that — nun, wife, ninety years old — is later legend, treated honestly on the Truth & Legend page. The song stops at the chronicle’s last note about her.
